I got a reply from DVloper. He IS working on the PC Version of the game.
With that said, I personally hope that there will be more to it than just a mirroring of the mobile version as is.
I personally would like to see more cutscenes and dialogues, and definitely an intro cinematic telling us about the fate of Previous Victim and Player, and why Granny actually has chained up her own daughter behind the bookshelf.
I also got some ideas about somehow making the Granny AI capable of learning the specific Player's playstyle, forcing the Player into altering his or her strategies.
And an option to let us pick an Item Location Preset, right now we have to skip through 4 to get to the one we want to playtest.
